I have noticed that I have an instantaneous CTD (with no error message) when pushing "M" to open a local map in an interior cell.

At first I though it could be an INI tweak, because I used some tweaks related to the map and the camera...but resetting the INI still caused CTD.

Now I am wondering...usually instantaneous CTD are related to maps, but I didn't use any mod related to interior cell maps...

I have the following load order...the amount of mods is huge, but surprisingly is quite stable (ok...a few CTD when running too much, but it's fine)...

RealSteelTweak.esp is just a silly mod of mine which adds a few crafting recipes, so it's not conflicting with anything...

If I run TES Mod Manager conflict detector I run in several conflicts, but what I understand is the following:

- LVLI conflicts are solved by Bash Patch.
- CELL and WRLD conflicts are bad, but should lead to weird things (people half-buried into stone and such).
- NPC_, ARMO, WEAPON, AMMO, RACE, INGR, ENCH, PROJ, RACE, MGEF, COBJ and PERK probably lead to overwriting.
- NAVI should be linked to navigation paths.
- QUST and DIAL should probably bad, but should not have any relationship with the local map...
- STAT, CONT, PACK, IDLE, AVIF, DOBJ, FLST, GMST, DHPT aren't clear to me...

The only conflic that seems related to local maps is the LCTN conflict...

...has anyone of you a better idea on how to understand which mod crashes the local map?

Thanks,

First disable all the mods, then put them on one by one to see which one crashes the game.

It's really bad news...

...detailed city is the cultprit.

Seems that there is an issue with the notorious navmesh bug.

Thanks,

Jashkar

Disabling isn't enough and that's a terrible process. First, mods need to be uninstalled instead of just disabled. Second, a binary search is much faster than a linear search. Third, mod issues belong here: http://www.gamesas.com/forum/183-skyrim-mods/
